備註

引發事件會透過委派叫用此事件處理常式。Raising an event invokes the event handler through a delegate. 如需詳細資訊,請參閱 < 處理和引發事件For more information, see Handling and Raising Events.

OnResize方法也可讓衍生的類別,而不需要附加委派處理事件。The OnResize method also enables derived classes to handle the event without attaching a delegate. 這是在衍生類別中處理事件的慣用技巧。This is the preferred technique for handling the event in a derived class.

給繼承者的注意事項

當在衍生類別中覆寫 OnResize(EventArgs) 時,請確定呼叫基底類別的 OnResize(EventArgs) 方法,使已註冊的委派能接收到事件。When overriding OnResize(EventArgs) in a derived class, be sure to call the base class's OnResize(EventArgs) method so that registered delegates receive the event. OnResize(EventArgs)可以呼叫方法,在建構期間,因此,如果您覆寫OnResize(EventArgs)可以在控制項的建構函式呼叫之前呼叫。The OnResize(EventArgs) method can be called during construction, so if you override OnResize(EventArgs) it can be called before the control constructor is called.
